I'm designing my chassis lockers and have the basic design sorted - the question is what to make them from? Choices are aluminium or composite panel, around 25mm thick.Weight and cost, little to choose between them, the panel would have a good insulation value, but I'm not sure how much of an advantage this would be.Both will be painted so appearance will be similar, anyone with any thoughts?Ivan C

I ended up making mine from 2mm steel sheet, but that was for ultimate strength really. I do envisage them getting a whack at some point in their life, even if it is in the near future down these tiny welsh lanes! I'm still not 100% sure whether it was the right choice vs aluminium, but it's done now and I'm happy with them fitted up.

It's got to be personal preference really, but I would advise making at least the door from higher gauge aluminium, to stand up to scrapes etc.

Mine are 3mm Aluminium - purchased from Metallics and then modified by myself to suit.Trying to get a reply from them regarding custom built lockers is almost impossible but if you can use one of their standard sizes and modify it yourself to suit your needs, it'll be delivered within a week!

Thanks Dave, I'm going with 3mm aluminium, I'll fabricate them myself as I know exactly what sizes I can accomadate and what I want to put in them.I also want an upgrade, security-wise, over whats available ready-made.Ivan C

A bit of real life advice. Whatever you make them from put adequate protection on the underside. My lockers are smashed to pieces and covered in dents on the underside from thousands of km on gravel roads.
